Three-dimensional display device

Abstract

A three-dimensional display device includes a liquid crystal display which has an image display surface which emits display light, a plurality of optical fibers, each of the optical fibers having a light-receiving end which receives the display light emitted from the image display surface and an emitting end which emits the display light, and a rotation device which rotates the optical fibers around a rotation axis perpendicular to the image display surface. The rotation radius of the light-receiving end and the rotation path of the emitting end of each of the optical fibers are set to have a one-to-one relationship.

1. A three-dimensional display device comprising:
 a display light source device which has an image display surface which emits display light; 
 a plurality of light-guiding members, each of the light-guiding members having a light-receiving end which receives the display light emitted from the image display surface and an emitting end which emits the display light; and 
 a rotation device which rotates the light-guiding members around a rotation axis perpendicular to the image display surface; 
 wherein a rotation radius of the light-receiving end and a rotation path of the emitting end of each of the light-guiding members are set to have a one-to-one relationship. 
 
   
   
     2. The three-dimensional display device according to  claim 1 , wherein the image display surface has a plurality of display pixels disposed along the rotation path of the light-receiving end of each of the light-guiding members. 
   
   
     3. The three-dimensional display device according to  claim 1 , the three-dimensional display device including a luminance correction mechanism which increases the luminance of the display light emitted from the emitting end as the rotation radius of the emitting end increases. 
   
   
     4. The three-dimensional display device according to  claim 1 , wherein one of the area of the emitting end of the light-guiding member, a diameter of the light-guiding member, and an area of the light-receiving end of the light-guiding member increases as the rotation radius of the emitting end increases. 
   
   
     5. The three-dimensional display device according to  claim 1 , wherein the number of the light-guiding members of which the emitting end has an identical rotation path increases as the rotation radius of the emitting end increases. 
   
   
     6. The three-dimensional display device according to  claim 1 , wherein the light-guiding member includes an amplification device which amplifies the display light.
